Construct Development With Rasch Model

The university's Post Graduate Students Association organized another round of Rasch Model workshop with Mr Saidfuddin, a Rasch Model consultant and facilitator. Some of ARI's post graduate students and research fellows attended the two-day event, which is held at the Tun Abdul Razak Library's IT laboratory. Rasch Model is particularly useful when developing a questionnaire survey which relies a lot on "ordinal" data sources. Through Rasch Model analysis, a pilot study can be analyzed more effectively as it is possible to determine if the "content" items have been sufficiently supported by relevant theoretical underpinnings. In addition, it is also possible to analyse if the respondents have been appropriately selected for the study. Hence, it is still possible to reconstruct the questionnaire by improving the items content, recategorize the dimension, collapsing the scales or to specify better target sample for the final questionnaire.
